General description
脲酶是一种催化尿素水解成二氧化碳和氨的酶。 脲酶存在于细菌、酵母和某些高等植物物种中。脲酶活性存在于环境和粪便样品中。
Application
脲酶活性测定试剂盒已用于测量脲酶活性。
适用于检测生物样品及环境样品中的脲酶活性。
Biochem/physiol Actions
在该测定中，脲酶催化尿素的水解，导致氨的产生。 通过 Berthelot 方法测定氨，导致在 670nm 处测量比色产物，与样品中存在的脲酶活性成比例。一个单位的脲酶是在 pH 7.0 下，每分钟催化形成 1.0 μmole 氨的酶量。
Features and Benefits
兼容高通量的操作系统。可在比色皿中使用。

We demonstrate for the first time that the morphology and nanomechanical properties of calcium carbonate (CaCO3) can be tailored by modulating the precipitation kinetics of ureolytic microorganisms through genetic engineering. Many engineering applications employ microorganisms to produce CaCO3. However, control
